Many organisms and animals have sensing abilities that are different from those of human beings; for example, snakes have strong smell-, vibration-, touch- and heat-sensing abilities. A nature-mimicking sensing platform capable of sensing multiple stimuli, such as strain, pressure, temperature and other uncorrelated conditions, is highly desirable to broaden the applications of sensors. Here, we construct a semitransparent intelligent skin-like sensing platform based on polyaniline (PANI) nanowire arrays that can act as a bionic component by simultaneously sensing tactile stimuli and detecting colorless, odorless gas. Our multifunctional bionic sensing strategy is remarkably adaptive for versatile applications. The strain-sensing performance is superior to that of most conducting polymer-based sensors reported so far and is comparable to or even better than traditional metal and carbon nanowire/nanotube-based strain sensors. The highest gauge factor demonstrated is 149, making our system a remarkable candidate for strain-sensing applications. The sensor can accurately detect a wide range of human motions. We also demonstrate the simultaneous controlled olfaction ability for the detection of methane with high sensitivity and a fast response time. These results enable the realization of multifunctional and uncorrelated sensing capabilities, which will afford a wide range of applications to augment robotics, treatment, simulated skin, health monitoring and bionic systems.

许多生物和动物具有与人类不同的感知能力。例如，蛇具有很强的嗅觉，振动，触觉和热感应能力。为了扩大传感器的应用，迫切需要一种能够模仿多种刺激（例如应变，压力，温度和其他不相关条件）的模仿自然的传感平台。在这里，我们构建了一个基于聚苯胺（PANI）纳米线阵列的半透明智能皮肤感测平台，该平台可以通过同时感测触觉刺激并检测无色，无味的气体来充当仿生成分。我们的多功能仿生传感策略非常适合多种应用。应变感应性能优于迄今为止报道的大多数导电的基于聚合物的传感器，并且与传统的基于金属和碳纳米线/纳米管的应变传感器相当甚至更好。所展示的最高规格因子为149，这使我们的系统成为应变传感应用的杰出之选。该传感器可以准确检测各种人体运动。我们还展示了用于甲烷检测的同时受控嗅觉功能，具有高灵敏度和快速响应时间。这些结果使多功能和不相关的传感功能得以实现，这将提供广泛的应用，以增强机器人技术，治疗，模拟皮肤，健康监测和仿生系统。所展示的最高规格因子为149，这使我们的系统成为应变传感应用的杰出之选。该传感器可以准确检测各种人体运动。我们还证明了同时控制嗅觉的能力，可以以高灵敏度和快速响应时间检测甲烷。这些结果使多功能和不相关的传感功能得以实现，这将提供广泛的应用，以增强机器人技术，治疗，模拟皮肤，健康监测和仿生系统。所展示的最高规格因子为149，这使我们的系统成为应变传感应用的杰出之选。该传感器可以准确检测各种人体运动。我们还证明了同时控制嗅觉的能力，可以以高灵敏度和快速响应时间检测甲烷。这些结果使多功能和不相关的传感功能得以实现，这将提供广泛的应用，以增强机器人技术，治疗，模拟皮肤，健康监测和仿生系统。我们还证明了同时控制嗅觉的能力，可以以高灵敏度和快速响应时间检测甲烷。这些结果使多功能和不相关的传感功能得以实现，这将提供广泛的应用，以增强机器人技术，治疗，模拟皮肤，健康监测和仿生系统。我们还证明了同时控制嗅觉的能力，可以以高灵敏度和快速响应时间检测甲烷。这些结果使多功能和不相关的传感功能得以实现，这将提供广泛的应用，以增强机器人技术，治疗，模拟皮肤，健康监测和仿生系统。
